(CNN) -- Louisiana Gov. Bobby Jindal declared a state of emergency Thursday in preparation for the arrival of an oil spill in the Gulf of Mexico that was expected to reach land Friday.

At the White House, President Obama said the federal government will use "every single resource at our disposal" to help contain the oil spill.

The U.S. military may be called on to assist authorities scrambling to mitigate the potential environmental disaster posed by the spill, officials said.

At a White House briefing Thursday, federal authorities, including Homeland Security Secretary Janet Napolitano, pledged a robust response. Napolitano said she has designated the leak a "spill of national significance," meaning officials can draw down assets from other areas to combat it.

Officials said late Wednesday the estimated amount of oil spewing into the Gulf from three underwater leaks after last week's oil rig explosion has increased to as much as 5,000 barrels, or 210,000 gallons, a day -- five times more than what was initially believed.

You're right.. we should stop drilling and buy foreign oil at a premium instead. Russia has the right idea, drill OUR oil (because we won't), then sell it back to us.

Not to mention the fact that when the Russians, Chicoms, and Castro regime drill in the same waters, we'll see a lot more of this. They don't put any value on the environment, whereas we at least try to avoid incidents like this.

Oh, and to our Cheaters fan, stay classy...this is real to people on the Gulf Coast whereas all you care about is using it to further your sick obsession with a former vice presidential candidate. You should be ashamed of yourself. THIS IS NOT A JOKE.
